This bulb is an improvement to IPFs existing Fatboy bulb by incorporating the latest in lighting technology that results in a brighter, but more efficient low and high beam. The Fatboy II Bulb uses an exotic high-pressure gas mix, coupled with a massive bulb envelope to create to
unrivalled brilliance. The unconventional bulb shape provides less loss of light from the filament. A stabilizer rod within the bulb extends the life of the filament even in the harshest of conditions.There are two different color options available, Super Clear and Max White and both are available in pairs or as a single unit.
